I would just go buy a core tool remover and re tighten all of em down.


What I find weird is that it was loose. They should of replaced all the stems as part of the service. There should be no reason that it was loose.

 

Hehehe. My buddy is picking one up for me in the city at the store as we speak. I run Work CR Kai wheels with the valve stems that came with them (the blue ones). I was thinking maybe the Work stems are aluminum and the cores the tire shop put in are steel. Could there be dissimilar metal corrosion going on causing the leak? Or did they just not tighten the core enough?

 

You will want to run the silver cores, not the brass ones. If the core appears to be the brass/goldish hue, you will want to replace those too.


The same thing happens with TPMS sensors if use use the brass cores. They just seize in there.

 

Mine are silver. I'll just tighten them all up.
